To-all whom zit may concern:

Be it known that I, GUY L. BAYLEY, of in the county of Allegheny and State of ennsylvania, have invented a cer- A tein new and useful Valve for Filters, of which 1 the following is a full, clear, and exact dethe scription, re rence being had to the accompanying drawings, forming part of this specification, in which- I Figure 1 is an elevation illustrating my improvement. Fig. 2 is a vertical sectional view of the valve, the parts being shown in position forsinglc-filtering. Fig. 3 is avertical sectional View of the same on the line III III of Fig. 2. Figs. 4, 5, 6, and 7 are horizontal sectional views of the same on the lines IV IV, V V, VI VI, and VII VII, resgiectively of Fig. 2. Figs. 8. 9, and 10 are orizontal sectional views of the same on the lines VIII VIII, IX IX, X K, respectively, of Fig; 14, 1garts being in posit on in each figure for don lei-filtering. Figs. 11, 12,an(l 13 are hori zontel sectional views on the lines XI Xi XII XII, aiid' XIII XIII, respectively, cf Fig. 16; the parts bein inclers with filtered Water from thetot cylinder. Fig. 1.4 is a vertical sectional view 'of the same, the arts bein shown in position for double-fi tering. Fig. 15 is a vertical-sectional viewof-the same on the l 1111 XV XV of Fi 14, the part-S being shown in position for double filtering. Fi 16 is a vertical sectional view of the same, t 35' the cylinders with'filtered water from the -otherc linder.

e parts being shown in osition for washing one of Fig. 17 is a vertical sectional view 0 the same on the line XVII XVIIof Fig. 16, the parts being shown in acsition for washing one of the cylinders w1th filtered be used to control and direct the flow of a. liquid through any one or through several of a. number 0 filters in various directions. Heretofole in the use of certain Water-fil ters there has been disturbance, of the filteringmaterial whenever the direction of the flow of water through the filter has been changed in passing from single to double filshown in each fi urc in position for was ing one of the c' g y li er. Water is caused to fmssfirst through one'filrotate the dial rotates therewit v to the casin of the valve is a points toning, or vice versa, and this disturbance is not only injurious to the filter itself, but it also renders the filtering operation more or less imperfect. There has also been more or less impure orxlirtywater passing to the serv icepipe after the wash ng operation has been concluded.

The object of my invention is to rovide a valve for changing the direction of the flow of liquid and also to change this ;direction in water-filters from single-filtering to double filtering, or vice versa, in such a. manner that the filtering material shall not be disturbed and also to change from washingtodoublefiltering in such a manner as to prevent any flirty Water passin to the service ipe.

In Fig. l of the drawings I heve s iovvn my valve applied to a filter ha twofilteringcylinders, the filter being of- =t.hs.t class" in which the water may be single-filtered-that is caused to divide into two streams, one of which is filtered in one cylinderandthe other stream is filtered in the other cylinder the filtered water from each cylinder passing into a csiiinion servicepipe, or the Water maybe douhlefilteredthat is, the entire stream of tering-cylinrler an then through the other filtering-c linder, and then in'tothe' servicepipean the filterin -cylinders may be washed each one Withffitered water fromv the other 0% the two cylinders.

I will now describe my invention so that others skilled in the art to which it spher tains may nranufactureand use the same.

In the drawings, A and representghe two filtering-cylinders and C represents m improved' vaive. Leading to the valve 0 IS the rew-water-supply pi e. 2:, and leading "from the valve (3 tojthe o 'nders A and B are, the sulgplypiies a and and leading from the cy' and B back to the valve 0 are the discharge-pipes a and b. Leedin from indel's the valve C is the service-v-pipe d ands so the wasteipef.

In t e drawings, Figs. 2, 14,16, and 18, I I

show a dial 1- so secured to the stem 7:. of the valve that as the stem andplu of the valve Fastened rorinklexr s. f his dial ismarked at it s middle tablet with the Word singlefiltcring, or with letters or figures indicating the same, which is the first or ordinary position ofthe valve. On one side of this middle tablet is a tablet marked Double-filtering right to left, or with letters or figures indicating the same, which is one of the second positions of the valve. On the other side of the middle tablet is a tablet marked Double-filtering left to right, or with letters or figures indicating the same, which. is the other of the second positions of the valve. At the two ends of the dial are tablets marked W'ashing right and "VVashing left, or letters or figures indicating the same, which are the third positions of the valve. These tablets when brought opposite the pointer 5 show the .position of the plug of the valve in the casing, such position being the proper one for the operation indicated by the tablet.

In Figs. 2 and 3, which are vertical sec tional views of the valve, and in Figs. 4, 5, 6, and 7, which are horizontal sectional views, I have shown the plug i of the valve in position to sin le-filter the waterthat is, the plug is in suc 1 position as to divide the water entering the valve-casing C from the raw-watersupply pipe 1: into two streams, one stream passing through the pipe (1- to the cylinder A and the other passing through the pipe b to the cylinder B. The valve-casing C is provided with a supply inlet-port 2, which connects with the supplypipe an, a supply outletport 3, which connects with the pi e a, lead ing to the cylinder A, a supply out ct-port 4, which is similar to the port 3 and connects with the pipe 1), leading to the cylinder B, a discharge inlet-port 5, which connects with the pipe at, leading to the valve from the bottom of the cylinder A, and a discharge inletport 6, which is similar to the port 5 and connects with the pipe 1), leading to the valve from the bottom of the cylinder B, a discharge outlet-port 7 that connects with the service-pipe d, and a washing or waste port 8, that connects with the waste-pi e f. The plug i of the valve is rovided'wit channels which may be broug t into communication with the several ports in the casing by turn ing the plug on its axis. In the positions of Figs. 2, 3, 4, 5, 6, and 7, which is the position for single-filtering, the sup ly inlet-port 2 is in communication with the supply-pipe m k and the supply outlet-ports 3 and 4 are in communication with the pipes a and b, and an open channel k, formed in the plug i, extends between the port 2 and the ports 3 and 4, thus permitting the water to pass from the su ply-pipe as to both cylinders A and B. A ter passing through the filtering material in the cylinders A and B the water passes from the cylinders through the pipes a and b to the discharge inlet-ports 5 and 6 in the valve-casing C and thence through the open channel 0 to the discharge outlet-port 7, which is in communication with the servicepipe d. In this plug 'i are four separate channels, of which the channel kthe upper of the ehannels-serves to direct the flow of water from the supply-pipe x to the supply outlet-pi es a and b, or either of them, through t re ports 3 and 4 in. the operation of single-filtering. A lower channel 711 conn'nunicates with either of the ports 3 and 4 and pipes c and b and also with the waste-port 8 and waste-yfipef. This channel is used solely for the purpose of washing the cylinders A and B. The third channel on comnnn'iicates with either of the supply outlet-ports 3 and 4 and with either of the discharge inlet-ports 5 and 6 and serves as a return-passage for filtered water from the bottom of either one of the cylinders A B to the top of the other cylinder in double-filtering. A fourth channel 0 communicates with the dischargeorts 5, 6, and 7 and serves as a passage for the filtered water from the cylinders A and B, either or both of them, to the service-pipe d.

The operation of these parts in double-filtering is as follows: The plug 1', of the valve bein in the position of single-filtering, hereinbe ore described, to double-filter from the cylinder A to the cylinder Bthat is, from right to left-the plug "L and the dial r are turned to the right until the tablet indicating Double-filtering right to left comes opposite the pointer s. This brings the plug of the valve to the position shown in Figs. 8, 9, 10, 14, and 15 of the drawings. In this position the supply inlet-port 2 communicates with the channel It and the channel is communicates with the supply outlet-port 3, openin into the pipe a and cylinder A, but is shut o from the supply outlet-port 4 by the partition 7c. The effect of this is that all the Water from the supply-pipe 9: passes to the pipe a and cylinder A, in which cylinder the water is single-filtered. In this position the discharge inlet-port 5 is in communication with the channel m, but is cut off by the partition m from the channel 0, with which it is in communication in single-filtering. This channel m is also in communication with the sup ly outlet-port 4 and pipe I), which leads to t e c linder B. A direct passage is thus formed om the bottom of the cylinder A to the top of the cylinder B, and the single-filtered water from the cylinder A passes through the cylinder B, where it is doublefiltered. The ports 6 and 7 are in communication with the channel 0, and after the water has passed through the cylinder B it asses to the service-pi e (1 through the dISCl iflIgB- pipe I) and the c annel 0 of the valve C.

The operation of washing the cylinder A is as follows: The dial 1" and plug 'i being in the position thus described--that is, for doublefiltering from right to leftthe dial 1" and plug t are given a further turn to the left, which brin s the tablet indicatin Washing ri ht-han cylinder opposite t e index 8. T is movement also brings the plug i of the valve 0 into the position shown by Figs. 11,

tests 12, 13, 16, and 17, in which position the chan nel 1c is in communication with the sup ly inlet-port 2 and also with the supply out etport 4 and with the pipe 5, leading to the cylinder B. This forms an 0 on channel between the supply-pipe a: an( the cylinder B, ermitting the water to pass to the cylinderB or single-filtering, and the water asses from the cylinder B, in which it is ltered, out throu h the pi e b and through the port 6 into t e channe o, This channel 0 is in communication with both the ports 5 and 6 and also with the port 7. Conscquentlypart of the single-filtered water entering through the port 6 passes to the service-pipe d through the port 7, and part of the single-filtered water passes through the port 5 and pipe a to the base of the cylinder A, where it passes through the filtering material from bottom to top. From the top of the cylinder A the dirty water, carrying the impurities, passes through the pipe a. to the port 3. This port 3 is now in communication with the washingchannel n, which channel is also in communication with the waste-port 8, which opens into the waste-pipe f. When the cylinder has been sufficiently washed, the dial and plug of the valve ma be turned back to the position of double-fl tering right to left, in which osition the water is directed first to the cylinder A, which has just been washed, and after assing through the cylinder A passes to t e c linder B. The result of this is that any dirty water or stirred-up sediment remaining in the cylinder A after the washing operation is deposited in the cylinder B instead of passing to the service-pi e d, as would be the case were the water to lie passed first through the unwashed cylinder and then through the washed cylinder containing the stirred-up sediment.

The operation of double-filtering left to right and washing the left-hand cylinder with filtered water from the right-hai1d cylinder is similar to the operations hereinbe fore described, the dial and valve, of course, being turned in the opposite direction.

The advantages of my invention result from the construction and arrangements of ports and channels that enables the flow of water to be changed from single-filtering to double-filtering, and vice versa, Without stirring up the filtering material and that enables the flow of water to be changed from washing to filtering without liability of carrying sediment from the washed 0 linder into the service-pipe and also from tll e construction and arrangement of the parts of the valve that enables the water to flow throu h the several ports and channels with litt e friction without liability of leakage.

I have given the several ports names in accordance with their functions in the first or single-filtering position of the valve, and these names have been retained throughout the specification and claim, although the functions may be different in the several positions of the valve.

Changes of form and coi'istrur'ztion may he made in the valve without departing from my invention. It also may be applied to other forms of iilters and to other uses than the filter shown and described in this specification.

In my copending application, Serial No. 258,703, filed MayS, 1905, I have described and claimed a construction similar to the present one, with the exception that in said construction upon the return movement of the plug of the valve from the third or washing position to the second or double-filtering position the discharge-inlet of the washed filtcring-chamher is connected to the discharge outlet-port leading to the service-pipe, whereas in the present case upon such movement of the dug the discharge inlct-port of the washed filter ing-chamber is connected with the outletport leading to the other filtering-chamber.

I claim-- The combination of two filterin -chamhers: a valve-chamber having a supply inletport connected to the raw-water-supply pi pe, two supply outlet-ports connected to said filtering-chambers, two discharge inlet-ports also connected to the filtering-chambers, a discharge outlet-port leading to the serv1cepipe, and a washin or waste port: and a plug adapted to said valve-chamber and provided with channels and ports adapted in the first or single-filtering position of the plug to connect said supply inlet-port with said two supply outlet-ports and said two discharge inletports with said discharge outlet-port; in the second or double-filtering positions of the plug to connect the supply inlet-port with the sup ply outlet-port leading to one filterin -chainher and the discharge inlet-port of saidiilterin -chamber to the supply outlet-port of the other filtering-chamber, and the discharge inlet-port of the last-named filterin chamber with the dischar e outlet-port lea ing to the service-pipe; and in the third or washing positions of the pin to connect the discharge inlet-port of one ltering-chamber with the discharge inlet-port of the other filtering-chamher and the supply outlet-port of said lastnamed filtering-chamber with the wastechannel and Wasteport and in the return movement of the plug from the third or washing positions to the second or double-filtering positions to connect the discharge inlet-port of the washed filtering-chamber with the sup ply outlet-port of the other filtering-chambe! 5 substantially as described.

In testimony whereof I have hereunto set my hand.
